Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155464, here are decompositions:
- 3 + 155461 = 155464
- 11 + 155453 = 155464
- 41 + 155423 = 155464
- 83 + 155381 = 155464
- 131 + 155333 = 155464
- 137 + 155327 = 155464
- 173 + 155291 = 155464
- 233 + 155231 = 155464
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 155,464 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 155464 first appears in π at position 197,329 of the decimal expansion (the 197,329ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
